论文摘要
许多图像处理操作涉及图像的空间频率内容的修改。在这里，我们通过商用光谱带滤波器滤波器的角度灵敏度演示了对象平面空间频率滤波。这种全光图像处理的方法显示出可产生透明生物学和其他样品（例如人宫颈癌细胞）的实时伪3D图像。这项工作证明了非本地，非接触方法的潜在图像处理用于无标签的生物细胞成像和动态监测的潜力。
Many image processing operations involve the modification of the spatial frequency content of images. Here we demonstrate object-plane spatial frequency filtering utilizing the angular sensitivity of a commercial spectral bandstop filter. This approach to all-optical image processing is shown to generate real-time pseudo-3D images of transparent biological and other samples, such as human cervical cancer cells. This work demonstrates the potential of non-local, non-interferometric approaches to image processing for uses in label-free biological cell imaging and dynamical monitoring.
